Tim: I don't know what name you may be listed in IMDb as, but the roman numerals are generally assigned in numerical order and are never reassigned unless IMDb needs to do so for their own internal purposes.

If you tell us how you are listed in IMDb, and how your name was spelled on screen in that 2012 film (i.e. not how it was entered into the database, but what it said in the credits on screen), we can advise you better about how to submit a correction.

I think any time there are more than one person with the same name, everyone gets a Roman Numeral. Even THE John Wayne, Clark Gable and Gary Cooper have Roman Numerals. The big names do somehow get the first number though, so that’s not random. There are dozens of Gary Coopers and the numbers are sort of by earliest activity but not always. I think for non-really-famous names it goes by order of creation, but I could be wrong. I’m guessing your name got spelled ‘Tim Yagar’ in ‘Red Courage’ so there is a very easy fix to that but you’ll end up as Roman Numeral (II). You still need to say if that was how your actual screen credit was shown, though, to determine whether you need an attribute added to your credit.

Nick and Owen: The difference is that long before IMDb started assigning roman numerals to names, John Wayne and Gary Cooper were already very famous. So when IMDb made their first assignments of roman numerals, they could choose to give (I) to those famous actors rather than to other people by the same name.

By contrast, the actress Emma Watson did not make her film debut until 2001, by which time there had already been another Emma Watson entered into IMDb. So the actress became Emma Watson (II).

(In the case of Clark Gable, the actor appears to have been the only person by that exact name in IMDb until 2014, when a boom operator with that name was added. So naturally the actor who was already in the database got (I) and the boom operator got (II), since he was chronologically later.)

Tim, we haven’t heard back from you for verification of your wrong name and film it was in. I suspect you were entered as “Tim Yagar” in Red Courage (2012). If you can verify this someone can correct it but as mentioned above you will end up as Tim Yager (II).

Thanks to everyone that replied and your flexibility in me getting back to the thread.

The credit comes from the short film Red Courage and my name "Tim Yager" was misspelled as "Tim Yagar". The production company has my name wrong on their site and you can see my name wrong on-screen here.

So it seems the best course of action is to submit a correction as "Yager, Tim (II)"?
